表达区间及表达系统（Source）
PE-Labeled Human HLA-A*11:01&B2M&HPV16-E7 (IVCPICSQK) Tetramer Protein (HL7-HP2H4) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*11:01) & Ile 21 - Met 119 (B2M) & IVCPICSQK peptide (Accession # Q5S3G3-1 (HLA-A*11:01) & P61769 (B2M) & IVCPICSQK).
Predicted N-terminus: Gly 25 & Ile 21
蛋白结构（Molecular Characterization）
PE-Labeled Human HLA-A*11:01&B2M&HPV16-E7 (IVCPICSQK) Tetramer Protein is assembled by biotinylated monomer and PE-labeled streptavidin.
Biotinylated Human HLA-A*11:01&B2M&HPV16-E7 (IVCPICSQK) Complex Protein is produced by co-expression of HLA and B2M loaded with HPV16-E7 peptide. Biotinylated Human HLA-A*11:01&B2M&HPV16-E7 (IVCPICSQK) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

背景（Background）
Human papillomavirus (HPV) is A kind of papillomavirus belonging to the milk polypoid virus family. It is a spherical D virus, which can cause the proliferation of squamous epithelium of human skin mucosa. HPV(human papillomavirus) for common warts, genital warts (condyloma acuminatum), and other symptoms. There are many types of human papillomavirus (HPV), with HPV 16 and 18 being high-risk types known to significantly increase the risk of cervical, vaginal and vulvar cancers in women and men. The PE-labeled human HLA-A*1101 HPV (IVCPICSQK) tetramer protein is a complex of HLA-A*1101 of the MHC Class I, B2M, and IVCPICSQK peptide of the HPV.
